I posted the thread I bought the knife from, the seller claimed it came back from Darrel's. I had the knife, and it locked. Pressing directly down on it it stayed locked. It was fine when I shipped it. So, here again, same claims. You just keep mixing it up to continue smearing. You want a refund or not. I keep saying lets continue this in email and you keep bringing it back. I'll sit here for another 2hours defending myself. Your first post you editted. Before editting it you said, YOU DID NOT WANT A REFUND. I still am offering a fix, but it will require you to send it back to me first.
The Paypal claim won't do anything. Your credit card will do a charge back. I'll file a claim with Paypal, Paypal defends the seller first. I have proof you received the knife. There is no formal invoice. Paypal gets the money back into my account. Money will go from me to you and back to me and it will take about a month. You file a claim, you lose. I don't care for that much as I am no thief nor care to rip anyone for $350, price you paid for that knife...
You want resolve, apologize for jumping on my name and posts and send me the knife back in the same condition I sent it to you. Otherwise I don't know what else to do.
